Regression of monolignol transcript/protein relationships. Transcript abundance is used in the linear regression equations (Supplementary Table 2) to obtain the predicted protein abundance (y-axis), which is regressed on the experimental protein abundance (x-axis). The equations can explain ~89% of the variation in abundance of the monolignol biosynthetic proteins in the 239 transgenic and wildtype samples, based on the abundance of the gene transcripts. Each data point represents the abundance of a monolignol gene for a replicate pool of one wildtype or transgenic line containing 3–5 clonally propagated plants
